LaueX performs the following tasks:
- simulation of a Laue diagram, from the knowledge of the orientation of the crystal, the cell parameters and the position of the detector. Note that LaueX is not limited to the transmission and reflection cases, but that the position of the detector may be located anywhere on a sphere centered on the crystal. This feature has been introduced for work done especially at synchrotron. If the structure of the crystal is known, the program may evaluate the intensities of the Laue spots, and draws them as spots which size is proportional to their intensity.
- indexation of an experimental Laue diagram, by the knowledge of the cell parameters and the position of a number of spots of low indeces.
- alignment of a crystallographic direction along an axis of the apparatus (usually the one pointing towards the X-ray source), or rotation of the crystal.
- printing of the simulated diagram in a PostScript file, or directly to a laser printer.
LaueX is designed for small UNIX workstations. It has been developed under AIX but may run with other UNIX operating system. It is written in C language. X-Window system and OSF-Motif widgets (Xm library) are required for the graphic user interface.
A X-window display is mandatory, but color is not necessary. The memory size of LaueX depends on the maximum number of spots for the simulation; with 3000 spots a memory size of about 2 Mb is needed. The disk space required for the installation of the software is about 6 Mb.
A documentation of about 1300 lines describes the program use, two examples and the installation procedure:
